摘要： A pneumatic lifting table frame and a lifting table, relating to the field of lifting mechanisms. The lifting table includes a transverse beam and columns, and further includes a pressure sensor that detects a load of the lifting table frame, a controller configured to receive a pressure signal from the pressure sensor, and an adjustable gas spring assembly configured to drive the columns to be lifted or lowered. The adjustable gas spring assembly includes an adjustable gas spring body, a gas reservoir, a piston rod assembly, and a drive unit. The adjustable gas spring body is connected to the gas reservoir via a gas pipe. The controller is configured to control the drive unit, the adjustable gas spring body is disposed in one of the columns, and the drive unit drives the piston rod assembly to carry out a piston motion in the gas reservoir. The lifting table frame has a better comfort, a longer service life, a higher stability, a stronger practicality, and a lower damage possibility.

摘要： Disclosed are a transmission assembly and a lifting column. The transmission assembly includes a first screw rod, a second screw rod, a first transmission sleeve fitted over the first screw rod, and an actuating device for driving the first transmission sleeve to rotate; an end of the first screw rod proximal to the actuating device is fixed, and an end of the second screw rod distant from the actuating device is fixed; a second transmission sleeve is disposed between the first screw rod and the second screw rod, the second transmission sleeve and the first transmission sleeve are synchronously rotatable and are axially extensible and retractable relative to each other, and both ends of the second transmission sleeve are in threaded transmission connection with the first screw rod and the second screw rod, respectively. Because no inner splines are provided for the first screw rod and the second screw rod, and the two screw rods do not rotate, bearings become unnecessary, such that the transmission assembly has a simpler structure, more convenient for manufacturing and assembling.
